React Navigation 速度非常慢

Question

在过去的 5 个月中，我们一直在开发的应用程序中使用 react-navigation。

从昨天开始，react navigator 开始导航到屏幕，延迟 4-8 秒。我已经删除了在 screenProps 中传递的所有变量，但它仍然存在相同的问题。

我正在通过检查执行 navigation() 函数之前和 componentWillMount() 之间的时间来测试延迟，我在两者之间获得 4-8 秒。任何更有经验的人都知道为什么 navigate() 需要这么长时间？

还没有对导航器进行一些更改，它刚刚开始以这种方式行事：|

我正在真正的 android 设备上进行调试模式测试，但我已经发布了一个版本进行测试，但延迟仍然存在。

我的导航器：

import React, { Component } from 'react';
import { createStackNavigator, HeaderBackButton, createAppContainer } from 'react-navigation';

import { colors } from 'assets/styles/colors.js';

import RegistrationInputScreen from 'components/Registration/Input.js';
import RegistrationVerificationScreen from 'components/Registration/Verification.js';
import MainScreen from 'screens/MainScreen';
import Conversation from 'components/Messages/Conversation';
import Private from 'components/FirstTime/Private.js';
import Description from 'components/FirstTime/Description.js';
import CategoriesScreen from 'components/FirstTime/CategoriesScreen.js';
import Professional from 'components/FirstTime/Professional.js';
import Home from 'components/Home.js';
import SecretScreen from 'screens/SecretScreen.js';
import Map from 'components/Map/Map.js';
import ProfileScreen from 'components/Profile/Profile.js';
import EditProfile from 'components/Profile/EditProfile.js';
import PublicProfile from 'components/Profile/PublicProfile.js';
import Settings from 'components/Profile/Settings';
import {setTopLevelNavigator, navigate} from './NavigationService';



export default class RootNavigator extends Component {
  constructor(props){
    super(props)
  }

  render() {
    console.log("PROPERTIES IN ROOT NAVIGATOR", this.props);
    return (
      <Navigator />
    );
  }
}

// ref={navigatorRef => {
//   setTopLevelNavigator(navigatorRef);
// }}
export const RootNav = createStackNavigator(
  {
    RegistrationOptions: {
      screen: Home,
      navigationOptions: {
        header: null
      },
    },
    RegistrationInput: {
      screen: RegistrationInputScreen,

    Description: {
      screen: Description,

    },
    Professional: {
      screen: Professional,
      navigationOptions: ({navigation}) => (setHeader('Professional', navigation))
    },
    Conversation: {
      screen: Conversation,
      navigationOptions: ({navigation}) => (setHeader(null, navigation))
    },
    Secret: {
      screen: SecretScreen,
      navigationOptions: ({navigation}) => (setHeader('Configure app', navigation))
    },
    Profile: {
      screen: ProfileScreen,
      navigationOptions: ({navigation}) => (setHeader('Profile', navigation))
    },
    Public: {
      screen: PublicProfile,
      navigationOptions: ({navigation}) => (setHeader('Profile', navigation))

    EditProfile: {
      screen: EditProfile,
      navigationOptions: ({navigation}) => (setHeader('Edit profile', navigation))
    },
    Settings: {
      screen: Settings,
      navigationOptions: ({navigation}) => (setHeader('Settings', navigation))
    },
  }
);

export const Navigator = createAppContainer(RootNav);

const setHeader = (title=null, navigation) => {
  let options = {
    title: title,
    headerStyle: {
        backgroundColor: colors.bgRed,
        shadowOpacity: 0,
        shadowOffset: {
            height: 0,
        },
        shadowRadius: 0,
        elevation: 0
    },
    headerTitleStyle: { color:colors.white },
    headerTransitionPreset: {headerMode: 'screen'},
    cardShadowEnabled: false,
    headerLeft: (
      <HeaderBackButton
        tintColor={colors.white} onPress={() => navigation.dispatch({ type: 'Navigation/BACK' }) }
      />
    )
  }

  if(title === null) delete options.title;

  return options;
}

这个问题又开始出现了，我的动画也非常慢。我发现禁用远程调试是导航器导航缓慢和动画缓慢的原因。如果其他人遇到这种情况，请尝试禁用远程调试。
